The Blues beat Watford 4-3 on Monday night and it was a celebratory atmosphere at Stamford Bridge after the club’s fifth Premier League title win was wrapped up last Friday.

Costa, who’d been named on the bench for this clash, decided to pass the time with a trip to the press room for a snack during the interval, and is said to have grabbed himself a piece of chocolate cake.

When asked about the incident, Conte said: ‘Which type of food? It’s very important this.’

After hearing it was chocolate cake, the Italian admitted he was ‘very angry’, though not out of concern for his players’ diet.
